I have an interesting algorithmic challenge in a project I am working on. I have a sorted list of coordinate points pointing at buildings on either side of a street that, sufficiently zoomed in, looks like this:
I would like to take this zigzag and smooth it out to linearize the underlying street.
I can think of a couple of solutions:
Is there a better or best way to approach this problem? (I am using Python 3.5)
Dali's post correctly surmises that a line simplification algorithm is useful for this task. Before posting this question I actually examined a few such algorithms but wasn't quite comfortable with them because even though they resulted in the simplified geometry that I liked, they didn't directly address the issue I had of points being on either side of the feature and never in the middle.
Thus I used a two-step process:
n=20
points specified (using this wonderful implementation).The result wasn't quite perfect but it was good enough:
Thanks for the help everyone!
